Punter57, I have always been wary of any method that relies solely on the PP from any particular sourse, and suggest that a way of minimising the risk of the "office boy" is to use the selection when your choice of 3 or 4 different sources have the same clear pick as fav. eg. Radio, Tab-form and say SMH, (don't know where they get their prices just picked those 3 at random).

Consensus picks are different I reckon that's dangerous ground.
Another one that doesn't make sense to me is when a method indicates certain days of the week, as, if it's a mechanical phenomenom, how can it work on Tuesday but not Thursday?? just food for thought.
